FILING MECHANISM FOR LETTER-FILES.

Specification of Letters Patent.

Patented Feb. 1, 1916.

Application filed July 8, 1915. Serial No. 38,811.

mechanisms for letter files and the like which are provided with aperforating attachment, operated by the lever of the said filingmechanism.

Vith the hitherto disclosed filing mechanisms of this kind theperforating attachment is disposed similar to the known perforatorsindependently between the stems of the filing pins, and is operated bylifting the lever of the filing mechanism, whereupon the letter, sheetof paper or the like may be introduced into the 'perforator; then thesaid lever is again depressed and thereby the paper is perforated. Forremoving the papers from the perforator and for filing them in the fileit is necessary to each time throw the said lever up and down. Filingmechanisms which are constructed on this principle do not afford intheir operation any advantages over the common filing mechanisms usedtogether with the common perforators, that is to say, when theperforating and the filing are performed as two separate operations, asthey require separate manipulations for each operation. lVith the objectof improving on filing mechanisms combined with perforators in thisdirection, the perforating attachment according to the present inventionis attached in such a manner to the filing mechanisms and of such adesign, that the perforation is performed simultaneously with the filingof the papers. For both operations,

therefore, only one single manipulation of I the lever of the filingmechanism by throwing it up and down is required, so that no sepa ateoperation is necessary for the perforation, as the perforation isperiormed by the work of filing.

For obtaining the object known perforating sleeves are displaceablyarranged on the stems of the filing mechanism and said sleeves areoperatively coupled in such a manner with the lever ofthe filingmechanism that when the latter is closed the said sleeves will perforatethe papers placed on the said stems, so that they are immediately filed,without requiring any further operation. For insuring an even filing ofthe papers a stop is provided between said stems on the level of thepoint at which the perforation is performed, so that the papers may belaid against said stop during the perforation.

The coupling between the perforating sleeves and the filing mechanism iseffected by means of a lever which may by means of two dogs fitted tothe lever of the filing mechanism lee-engaged with or disengaged fromthe perforating sleeve. The arrangement is such, that the dog operatingsaid lever when the filing mechanism 1s being closed, can come intoaction only when the bridges of the filing mechanism have alreadyreached the upper ends of the straight filing stems, so that the paperis steadily held during the perforating operation.

In another embodiment of the file the stop is movable, so that it maynot obstruct the manipulations in filing and pressing down thepapersyand it is coupled in such a manner with the closing andperforating mechanisms that when the mechanism is closed and the paperstherein are perforated, it will be automatically moved away from itsoperative position, and when the mechanism is again operated, it isagain automatically moved back into operative position.

In the accompanying drawings two embodiments of the present inventionare exemplified. i

Figure 1. is a front elevation of the closed 'iechanism. Fig. 2 is thesame view of the open mechanism. Figs. 3 and 4: are similar sideelevationsand Fig. 5 isa plan view of the mechanism. Figs. 6-8illustrate another embodiment, Fig. 6 being the. front elevation of thefile opened with the perforating attachment under tension, and Fig. 7

a similarvlew of the two mechanisms at the opposite terminal position.Fig. 8 is a front ele ation of Fig. 7 showing the operative position ofthe stop in dotted lines.

The filing mechanism which is fitted in known manner 'in a letter fileor the like, consists, as usual, of the base plate 0., the straightfiling stems Z) and the swiveling bridges c with the lever (Z. Thebridges c normally held out of alinement with the stems b by means of aspring 2, Figs. '3 and 4;. which is mounted on the base plate a. Bymeans of lever, (Z, the bridges are rocked to and fro in the knownmanner, for opening and. closing the filing mechanism, re spectively. l

According to the present invention perforating sleeves 0 are slidablyfitted on the filing stems b. The said sleeves 0 are connected to eachother at their lower end by means of a plate 39. Under this plate isdisposed a flat spring 2' or the like, which tends to hold the saidsleeves 0 in the raised position shown in Fig. 1. To a plate or the likeattached to lever (Z is linked a dog 6, which has below a beveledpressing edge. At both sides of this dog 6 the pins 7 and g are fittedto the lever (Z in such a manner, that when the lever is lifted the pin9 and when the lever is pressed down the pin 7 will strike against dog 6and move the same in the one or the other direction, respectively.

Between the stems of the filing mechanism is disposed the stop orabutment frame h, which allows of perforating papers at a constantdistance from their rear edge.

The operation of the filing mechanism is as follows: Vhen the lever (Zis lifted, that is to say, when the mechanism is opened the dog 6 ispressed forward by pin 9 and with its lower edge it rides on the plate72 press ing same downward, and with it the perforating sleeves 0against the action of spring 2. Thereby also the bridges c are swungback in the usual manner, so that the filing mechanism is opened (Figs.2 and at). Now he paper, letter or the like, to be filed is inserteduntil it bears with its rear edge against or enters into the upper partof the abutment frame h. hen, now, the lever (l is pressed down, thebridges c are again swung forward in the known manner and meet thestems'b, whereupon the pin f bears against the dog 6 moving the samebackward so that the plate 79 is released and is forcibly pressed upwardtogether with the perforating sleeves Q by the action of spring 2'. Thesleeves 0 perforate the paper so that the latter may simply he slippeddown and filed.

In the embodiment shown in the drawing the dog 6 is provided with acut-away portion or a slot, in which the pin 7 engages during thedownward throw of the le er (Z un il the filing mechanism has beenclosed, that is to say. until the bridges 0 have met the stems b. Thesame obiect might also be o tained by suitably arranging a pin f or by.

other means.

In the embodiment shown in Figs. 6-8 the stop or abutment frame consistsof a straight grooved bar 7' which is attached to two supports 20. Thesesupports are pivotally fitted to the baseplate of the mechanism andprovided with arms 00, which are hinged to the connecting plate 79 ofthe two perforating sleeves 0. A pluralit of springs 3 are interposedbetween the plate 7?. and base plate a for normally forcing the sleevesupwardly on the stems 0.

When the mechanism is opened, and the plate 72 is in its lowestposition, the springs are thus under tension (Fig. 7), and the stop hasthe operative position shown by dotted lines in Fig. 8. l Vhen themechanism is closed, the plate 2) is released and moved upward by theaction of the springs, so that the arms 00 of the supports w linkedthereto are carried upward and the stop is moved back into the positionindicated by full lines in Fig. 8. The stop is again automati callymoved back into its operative position when the mechanism is opened, aswill'be clearly evident from the drawing.
